    The concept of Bladeless Wind Turbine appears interesting! When will you launch a fully tested product with a performance better than traditional turbines? Congratulations for the achievements till date!

      Dear Ajay, thanks! We still have a hard path to walk before we can have a product in the market. But about performance, we never said we have better performance than regular wind turbines. Blades-based horizontal axis aerogenerators are a very mature technology which had years and years of development and optimisation. We don’t want to be competitors, but a small-wind alternative for an easier on-site generation on residential, rural or infrastructure uses.

    Hi team, we are electrical engineering students from Usman institute of Technology, Pakistan. we are working on our final year project that is totally relevant to Vortex Bladeless Wind Turbine, so we are in need of some details regarding vortecx bladeless turbine, can you please help us in this matter?

      Dear friend, we are currently working on a model of 2,75m high and an estimated nominal of 100w. Bigger devices will be developed in the future, but this is the device endorsed by the EU and the one we want to humbly launch as our first commercial product.

    Very interesting. As all high objects are vulnerable to lightning: have you thought of this and can you protect the rod against lightning without influencing its productivity?

      Yes! With the materials we are using Vortex turbines are not more vulnerable to lightnings than other tall structures (antennas and such). A regular lightning rod should do the job 🙂

    I have my final year project on vortex bladeless turbine. I am making a protype of this. The height of my mast is 1.5 m and what should be the wind speed? Is there any relation bw wind speed and mast height? I have to generate power of 5-7 W. And kindly guide me how mast produces vortex shedding effect and where should the wind strike the mast?

      Dear friend, the whole aerodynamic profile of the mast determines the behavior of the device on a range of wind speeds. The power generated grows with cubed height, therefore the higher, the more energy can harness from the wind and the more conversion to electricity. The wind range in which a Vortex turbine can work depends on the mast’s geometry and on our patented tuning system, which is able to modify the elasticity constant of the whole system.

      You can calculate the rigidity of the flexible rod and the overall weight and height of the device for an specific wind speed, this way you will get much more energy but just on that wind speed. If you want a Vortex turbine to work on a range of speeds you need something like our tuning system. You can read more about it here Tech Paper.

      About Vortex shedding, it is a complex phenomenon created around the whole mast. In this case, the air does not “strike” the mast, but flows around like on a wing. Give or take, the vortex street effect is a consequence of this airflow passing around a slender and rounded structure like Vortex’s masts.

      To sum up, the combination of the geometry, weight, and height of the mast, the rigidity of the rod, and calibration of the tuning system are what make Vortex turbines work. To reach more efficiency on your prototype you should mind those features.

    Hello, i am following you sine a fee years. Your technology is really fantastic and smart. I wouls like to know when you are planning to enter in the italian market and if there is a chance to buy sharess in the stock exchange.

      Thanks! We are right now under certification and planning industrialisation. If everything goes as expected we think first products might be offered for late 2019 / early 2020.

    What is overall cost to install in india

    • Vortex Bladeless
      Posted at 16:56h, 24 September Reply

      Dear friend, installation costs depend on the installation company and may be very different on each country. To calculate an average price you can investigate other services of renewables installations and check how much do they cost.

    Been following vortex since the beginning and have 3D model as well..
    I am very interested in installing one in my house here in Southern California if it work then I would want more in Costa rica where I live as well…
    I currently support 14.5 KW solar, and 4 Tesla power walls…. so I am essentially off the grid in suburbia ….
    Keep pushing forward….

    The energy in the wind is proportional to the capture area, and proportional to the cube of the wind speed.
    So your wiggle stick won’t really produce any useful amount of energy, will it…

      Hi! That principle you described well is suitable to every wind generator. It’s correct that the capture area of bladeless turbines is lower than the one of rotating wind turbines of same height. On the other hand, a small and concentrated capture area with no interference between nearby turbines means that you can put a bunch of Vortex aerogenerators quite close in the same area as a single regular turbine occupies to work and turn, compensating this way a lower capture area for a single device 🙂

      The power generation grows exponentially with height, and higher devices can work in higher wind speeds. The capture area for a single Vortex Tacoma (2,75m) is expected to have a nominal of 100w at the moment, working on a nice lock-in range. It is possible to reach more power but reducing the lock-in range.

        Perhaps factually quantifying voltage and current (power output) over a given wind speed would provide a basis for reality.

          A power curve 🙂 we have calculated many based on simulations and estimations from wind tunnel trials since beginning. But those are not “real” since the testing prototypes are not the final product. At current moment we are in certification stage with a third party company and trying to find an efficient way to industrialise the manufacture of the pieces. If the specs of some pieces change to be industrialised, the power curve will change. It also depends on the calibration of the lock-in range which may be adapted to be different for each area. If during the certification they find any problem, we will have to change the design as well. To sum up, we wanna publish info that can be applied to the future product we will sell, not to the developing prototypes that are still changing a little everyday. I hope you find this reasonable, a datasheet of Vortex Tacoma will be published asap!

    David, you might be interested in the ‘kinetic charging device’ invented by my friend, Paul Faso, you can visit his site at Evur to learn about this system of using kinetic motion to produce power. I have no doubt that Paul will want
    to dialog with you about possibly creating a hybrid system for power generation.

      Hello Greg, kinetic charging systems for cars like “regenerative breaking” is a well known technology. It looks curious that this Evur car claims to produce more than it consumes working as a car, a little bit contradictory, isn’t it?

    Hi Vortex !!!

    Long time without hearing from you !

    At what stage is the project running ? Any estimations regarding Time -To -Market ?

    Can BladeLess compete with traditional blade turbines in terms of cost/ production ? ( No doubt BladeLess wins from the enviromental point of view)

    Loved the old address… Even worked for some neighbours, but I hope the re location to an industrial area means going ahead in the development of future manufacturing & sales project.

    Kindest regards !!!

    Carlos

      Thank you Carlos! We are in the certification stage with the EU for the Vortex Tacoma (2,75), which takes several months. Of course we want to be in the market asap, in fact we need to because our current funding (european commision h2020) is not lasting forever. But good things always take time!
      Bladeless turbines are expected to be more cost-effective than regular turbines in terms of kWh/year compared to its costs. Since bladeless turbines are almost maintenance-less, they reduce costs drastically. But of course you should measure these things specifically for each location, each local energy costs and each wind conditions.

    pretty interesting idea 🙂 I don’t get details since I’m no engineer but I know enough to understand what you re talking about. Congrats for the hard work
